Snap on storm windows



Nov. 8, 1966 w. H. YANCEY SNAP ON STORM WINDOWS Flled March 20, 1964 INVENTOR. W/zz/AM A. )im ca United States Patent 3,283,804 SNAP ON STORM WINDOWS William H. Yancey, 170 W. Main Ave., Gastonia, NC. Filed Mar. 20, 1964, Ser. No. 353,351 6 Claims. (Cl. 160-106) This invention relates to storm windows adapted to be snapped onto and off of window screens.

The primary object of the invention is the provision of strorn windows of the kind indicated, designed either for one-time or repeated use, and for either inside or outside installation, which do not require additional hardware for their installation and securement in place, and which, when installed, provide imperforate and substantially non-conductive barriers to the transfer of either heat or cold between the room or rooms served by them and the outdoors or other areas, so that desire-d existing temperature within the rooms are provided without substantial loss.

Another object of the invention is the provision of storm windows of the character indicated above, which are preferably formed of plastic material, adapted to be cut with scissors to desired widths, which can be either of light gauge for ordinary use or of heavy gauge for use in hurricane areas, and either clear or colored or opaque.

A further object of the invention is the provision of storm windows of the character indicated above, which are formed, on opposed edges, preferably the upper and lower edges of the storm window, with snap-on hooks adapted to be snapped onto and off of corresponding edges of window screens, without interference with the retaining or other hardware of the screens, the hooks being varied in form for mounting the storm windows on different types of window screens, both wooden and metal, including screens of double-hung windows, tension type aluminum screens, casement or awning type windows, as well as screen doors.

A still further object of the invention is the provision of storm windows of the character indicated above, which, in the case of heavy gauge hurricane resistant forms, the storm windows are adapted to have snap-on hooks on all four edges.

In the drawings:

FIGURE 1 is a perspective View of one form of storm window of the present invention;

FIGURE 2 is a contracted and fragmentary vertical transverse section taken through a window structure involving a wooden frame screen and retaining hooks therefor, showing the form of storm window of FIGURE 1 installed; and

FIGURE 3 is a fragmentary perspective view, partly broken away and in section, showing another form of storm window of the invention positioned for installation on a clip-retained metal window screen.

Referring in detail to the drawings, and first to FIG- URES 1 and 2 thereof, a sash window structure, is engaged against an external shoulder on which a wooden frame window screen 12 normally bears, and is held in place, at the upper end of the screen, by one or more spaced and pivoted spring fingers 14, and at its lower end, by several spaced hook-and-eye assemblies, including eyes 16 secured in the screen frame 18, and hooks 20, secured on the sill 22 of the window structure.

Mounted on the screen 12, to the inner side thereof, is a storm window 24, seen in detail in FIGURE 1, which comprises a preferably integral construction, comprising a rectangular panel 26 of the same outside dimensions as the screen frame 18, formed, on its upper edge, with spaced snap on hooks 28, and on its lower edge, with a single uninterrupted snap hook 30.

The upper snap-on books 28 are L-shaped and are composed of horizontal lateral flanges 32, which terminate in pendant vertical flanges 34, these flanges being resilient. The pendant flanges 34 are preferably spaced from the panel 26, at such a distance that when the snap hooks 28 are snapped over the upper edge of the screen frame 18, they spread and then resile, so that the pendant flanges 34 bear against the outer side of the frame 18, under tension. The upper hooks 28 are preferably located at the ends of the top of the frame 18 and are otherwise spaced and arranged so that they do not interfere with the spring fingers 14.

The continuous lower snap-on hook 30 is formed like the upper hooks 28.

In order to eliminate interference with the hook-andeye assemblies, the panel 26 is formed adjacent to its lower end, with spaced horizontal slots 36, through which the eyes 16 freely extend. It is to be noted that the storm window 24 can as readily be installed on the outer side of the window screen 12, in which case, the lower part of the screen frame 18 covers the slots 36.

With reference to FIGURE 3, showing a window screen 38, involving a channel metal frame 40, having a peripheral lateral flange 42, which would interfere with installation of a screen having L-shaped hooks, the frame 40 being retained in an associated window structure 44, by means of pivoted retainers 46, carried by tightening screws 48 threaded into the structure 44, along the sides of the frame 40.

For use with screen 38, another form of storm window 50, shown in FIGURE 3, is used, which comprises a panel 52, of the outside dimension of the main part 54 of the screen frame 40, having along its upper and lower edges, snap-on hooks 56, and along its side edges, snap hooks 57. The snap-on hooks 56 and 57 are continuous and extend the lengths fo the related edges of the panel 52, and are composed of single lateral horizontal flanges 58 which have concave upper surfaces 60' and convex lower surfaces 62. The hooks 56 and 57 are resilient and are tensioned inwardly, relative to the related edges of the panel 52, so that, in installing the storm window 50 on the screen frame 40 with the retainers 46 out of the way, the hooks 56 and 57 are spread outwardly by forcible contact with the outer surfaces 64 of the frame 40, so that the convex surfaces 62 of the hooks then resile and securely engage these outer surfaces. Where, as shown in FIGURE 3, the outer surfaces 64 of the screen frame are concave, the convex surfaces of the hooks 56 and 57 become securably seated in these concavities. The retainers 46 are then brought to bear upon the panel 52.

It is obvious that by slightly modifying the herein illustrated forms of snap-on hooks, the storm windows are readily adaptable for installation on window screens of forms other than those herein illustrated.

What is claimed is:

1. In combination, a window structure, comprising a window frame, a window screen having a frame engaged in the window frame, said window frame having a shoulder, said screen frame having opposed members normally bearing against said shoulder, said screen frame having outer edges, first means retaining the screen frame in place, a substantially imperforate panel of substantially the same outside dimensions as the screen frame and engaged with one side thereof, and resilient snap-on hook means on edges of said panel and securably engaged over outer edges of screen frame members and positioned between the screen frame and the window frame, and between the window frame and said shoulder.

2. The combination of claim 1, wherein said one side of the screen frame is the inner side thereof, with the panel compressed between said inner side and said shoulder.

3. The combination of claim 1, wherein said one side I of the screen frame is the outer side thereof.

5 panel compressed between said inner side and said shoulder, said retaining means comprising a hook-and-eye assembly comprising a hook pivoted on the window structure and an eye fixed to the screen frame and extending inwardly therefrom, said storm window panel being formed with slot means passing said hook.

5. The combination of claim 1, wherein said first retaining means comprises a retainer pivoted on the window structure alongside of the screen frame and normally overlying the frame and engaged therewith, said retainer overlying and being engaged with the side of the panel remote from the frame, said snap-on hook means comprising lateral flanges on edges of the storm window panel overlying and tensioned against outer edges of the screen frame.

6. The combination of claim 1, wherein said first retaining means comprises a retainer pivoted on the window structure alongside of the screen frame and normally overlying the frame and engaged therewith, said retainer overlying and being engaged with the side of the panel remote from the frame, said snap-on hook means comprising lateral flanges on edges of the storm window panel overlying and tensioned against outer edges of the screen frame, said outer edges being concave and said flanges having convex inner sides engaged in the concavities of the outer edges, said snap-on hook flanges being on the upper and lower edges of the panel.
